Description

Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to an all-terrain vehicle. Background Technology

[0002] An all-terrain vehicle (ATV) is a vehicle designed to travel on a variety of complex terrains. ATVs have strong off-road capabilities and can easily handle complex terrains such as mud, sand, snow, and rocks.

[0003] All-terrain vehicles typically include a frame, body panels, running gear, suspension system, powertrain, transmission system, seats, cargo box, and roof. The roof covers the top of the frame and is used to seal the all-terrain vehicle.

[0004] However, the roofs of existing all-terrain vehicles are difficult to remove, limiting them to either fully enclosed (cargo box not exposed) or partially enclosed (cargo box exposed) models. Furthermore, since the roof also seals the all-terrain vehicle, its sealing performance is crucial. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the purpose of this application is to provide an all-terrain vehicle with a roof that is easy to install and remove, and a roof with good sealing performance.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] An all-terrain vehicle includes a frame, a canopy, a running gear, and a powertrain. The frame includes a connected upper frame and a lower frame. The upper frame includes a front pillar, a rear pillar, and a top bar structure located above the front and rear pillars. The canopy is at least partially mounted on the top bar structure. The running gear is at least partially located below the lower frame. The powertrain is supported by the lower frame and is drive-connected to the running gear. The frame also includes a rear frame located behind the rear pillar. The canopy includes a front canopy and a rear canopy. The front canopy is mounted on the top bar structure, and the rear canopy is mounted on the rear frame. When the rear canopy is installed, the rear frame is connected to the rear pillar, and the rear canopy cooperates with the front canopy to seal the all-terrain vehicle. When the rear canopy is removed, the rear frame is separated from the rear pillar.

[0008] Furthermore, the all-terrain vehicle also includes seals, with the front and rear roofs sealed by the seals.

[0009] Furthermore, the rear end of the front roof is at least partially recessed downward to form a water channel, the water channel extending along the width of the frame and communicating with the outside, and the front end of the rear roof is at least partially located in front of the water channel and abuts against the front roof.

[0010] Furthermore, a first roof sealing surface is formed at the rear end of the front roof. The first roof sealing surface is located behind the water guide groove. Along the height direction of the vehicle frame, the seal is located between the first roof sealing surface and the lower surface of the rear roof. Along the width direction of the vehicle frame, the width of the first roof sealing surface is basically the same as the width of the front roof.

[0011] Furthermore, a second roof sealing surface is formed at the rear end of the front roof. The second roof sealing surface is located in front of the water guide channel, and the part of the rear roof in front of the water guide channel is sealed with the second roof sealing surface by a seal. The width of the second roof sealing surface is basically the same as the width of the front roof along the width direction of the frame.

[0012] Furthermore, the all-terrain vehicle includes a cargo box, and the rear frame is detachably connected to the cargo box. The all-terrain vehicle includes a first form with the cargo box exposed and a second form with the cargo box covered. When the all-terrain vehicle is in the first form, the rear frame is separated from the cargo box, and the rear roof is in a disassembled state. When the all-terrain vehicle is in the second form, the rear frame is connected to the cargo box, and the rear roof is in an installed state.

[0013] Furthermore, the all-terrain vehicle includes a cargo box, and the rear frame includes a first longitudinal frame, a second longitudinal frame located below the first longitudinal frame, and a vertical frame for connecting the first longitudinal frame and the second longitudinal frame. The vertical frame is located behind the first longitudinal frame and the second longitudinal frame. The first longitudinal frame is detachably connected to the rear upright, and the second longitudinal frame is detachably connected to the cargo box. The first longitudinal frame and the second longitudinal frame extend substantially along the length of the vehicle frame.

[0014] Furthermore, there are two rear frames, which are distributed along the width of the frame. The top beam structure includes a crossbeam, and the two rear frames are detachably connected by the crossbeam.

[0015] Furthermore, the second longitudinal frame, the vertical frame, and the rear column are all sheet metal parts. The second longitudinal frame, the vertical frame, and the rear column work together to form a glass sealing surface for installing glass, and the glass sealing surfaces are basically on the same plane.

[0016] Furthermore, the first longitudinal frame, the second longitudinal frame, and the vertical frame are integrally formed.

[0017] The roof of the aforementioned all-terrain vehicle includes a front roof and a rear roof. The rear roof has an installed state and a disassembled state. When the rear roof is in the installed state, it cooperates with the front roof to seal the all-terrain vehicle, thereby improving the roof's sealing performance. When the rear roof is in the disassembled state, it enables the all-terrain vehicle to be converted into different vehicle types, which is beneficial for meeting different usage needs and improving the ease of roof installation and removal.

[0031] like Figures 1 to 2 As shown, this application provides an all-terrain vehicle 100, which includes a frame 11, a body panel 12, a running system 13, a suspension system 14, a powertrain 15, and a transmission mechanism 16.

[0032] To clearly illustrate the technical solution of this application, the following are also defined: Figure 1 The directions shown are front, rear, left, right, top, and bottom. In this application, the length direction of the frame 11 refers to... Figure 1 In the fore-and-aft direction, the width direction of the frame 11 refers to... Figure 1 The left and right directions in the middle, and the height direction of frame 11 refers to Figure 1 The up and down directions in the middle.

[0033] The frame 11 serves as the basic framework of the all-terrain vehicle 100, supporting the body panels 12, the running gear 13, the suspension system 14, the powertrain 15, and the transmission mechanism 16. The body panels 12 are at least partially connected to the frame 11. The running gear 13 is at least partially located below the frame 11, and the suspension system 14 connects the running gear 13 to the frame 11. Specifically, the running gear 13 includes a front wheel 131 and a rear wheel 132, both of which are connected to the frame 11 via the suspension system 14. The powertrain 15 is drive-connected to the running gear 13; specifically, the powertrain 15 can be drive-connected to at least one of the front wheel 131 or the rear wheel 132.

[0034] Specifically, the frame 11 includes a front frame 111, a middle frame 112, and a rear frame 113 connected in sequence. Along the length of the frame 11, the middle frame 112 is located between the front frame 111 and the rear frame 113. The body panel 12 is at least partially connected to the middle frame 112 and forms a driver's cab 20 with the middle frame 112, the driver's cab 20 being used to provide seating space for the driver and / or passengers.

[0035] like Figures 2 to 4 As shown, in one embodiment, the frame 11 includes an upper frame 110 and a lower frame 11b connected together. The upper frame 110 includes an upper frame body 1105 and a front upright 1102 and a rear upright 1104 connected to the upper frame body 1105. The lower frame 11b includes a lower frame body 11bd and a front support column 11ba and a rear support column 11bc connected to the lower frame body 11bd.

[0036] The frame 11 also includes a top strut structure 115, which is located above the front pillar 1102 and the rear pillar 1104. The all-terrain vehicle 100 also includes a body sealing structure 24 (see reference). Figure 6 The vehicle frame 11 includes a cargo box 27. The cargo box 27 is located at least partially at the rear of the vehicle frame 11 and is used to carry cargo. A body sealing structure 24 is used to seal the all-terrain vehicle 100. The body sealing structure 24 includes a roof 242, which is mounted on a top bar structure 115 so that the top bar structure 115 can support the roof 242.

[0037] The frame 11 also includes a rear frame 119 located behind the rear pillar 1104, the rear frame 119 being at least partially located above the cargo box 27. The rear frame 119 includes a connected state and a disassembled state.

[0038] When the rear frame 119 is in the connected state, it connects the rear pillar 1104 and the cargo box 27. The rear frame 119 also cooperates with the roof support structure 115 for mounting the roof 242. When the rear frame 119 is in the disassembled state, it separates from the rear pillar 1104 and the cargo box 27. This configuration allows the all-terrain vehicle 100 to become a semi-enclosed model with the cargo box 27 exposed when the rear frame 119 is separated from the rear pillar 1104, and a fully enclosed model with the cargo box 27 covered when the rear frame 119 is connected to the rear pillar 1104. This allows the all-terrain vehicle 100 to switch between semi-enclosed and fully enclosed models according to usage needs, thus meeting different usage requirements and improving the practicality of the all-terrain vehicle 100.

[0039] Specifically, the rear frame 119 includes a first longitudinal frame 1191, a second longitudinal frame 1192, and a vertical frame 1193. The second longitudinal frame 1192 is located below the first longitudinal frame 1191, and both the first and second longitudinal frames 1191 and 1192 extend substantially along the length of the frame 11. The vertical frame 1193 is connected to the first and second longitudinal frames 1191 and 1192 at both ends along the height direction of the frame 11, so that the vertical frame 1193 can connect the first and second longitudinal frames 1191 and 1192, and the vertical frame 1193 is located behind the first and second longitudinal frames 1191 and 1192. In this embodiment, the first longitudinal frame 1191 is detachably connected to the rear pillar 1104, and the second longitudinal frame 1192 is detachably connected to the cargo box 27. This arrangement allows the rear frame 119 to be detached and installed from the frame 11, enabling the all-terrain vehicle 100 to switch between a semi-enclosed and a fully enclosed model.

[0040] More specifically, there are two rear frames 119, distributed along the width of the frame 11. The top beam structure 115 includes a crossbeam 1152. The two rear frames 119 are detachably connected by the crossbeam 1152. The crossbeam 1152 includes a first crossbeam 1152b and a second crossbeam 1152c located behind the first crossbeam 1152b. The two rear frames 119 are detachably connected by the second crossbeam 1152c. This arrangement allows the second crossbeam 1152c to connect to both rear frames 119, thereby improving the connection stability of the rear frames 119 on the frame 11. Furthermore, when disassembling the rear frames 119, the second crossbeam 1152c can be disassembled simultaneously, thus facilitating the fulfillment of different usage requirements of the all-terrain vehicle 100.

[0041] In one embodiment, the second longitudinal frame 1192, the vertical frame 1193, and the rear column 1104 are all sheet metal parts. The second longitudinal frame 1192, the vertical frame 1193, and the rear column 1104 are fitted together to form a glass sealing surface 1194 for mounting the glass. This arrangement, due to the good ductility of sheet metal parts, facilitates the machining of the glass sealing surface 1194 on the second longitudinal frame 1192, the vertical frame 1193, and the rear column 1104, allowing the glass sealing surface 1194 to seal against the glass.

[0042] Specifically, the glass sealing surface 1194 is basically on the same plane. This arrangement can prevent the glass from not being on the same plane due to unevenness of the glass sealing surface 1194, thereby preventing misalignment between the glass and the glass sealing surface 1194 during assembly and improving the sealing performance between the glass and the glass sealing surface 1194.

[0043] More specifically, the first longitudinal frame 1191, the second longitudinal frame 1192, and the vertical frame 1193 are integrally formed. With this configuration, the integrally formed components do not require assembly, which helps to ensure that the glass sealing surfaces 1194 of the second longitudinal frame 1192, the vertical frame 1193, and the rear column 1104 are on the same plane, thereby improving the sealing performance between the glass and the glass sealing surfaces 1194.

[0044] like Figure 5 As shown, in one embodiment, the frame 11 includes a rear frame 113 for carrying the cargo box 27. The cargo box 27 includes a cargo box panel 271 and a fixing pipe 272. The fixing pipe 272 is fixedly connected to the rear frame 113, and the cargo box panel 271 is fixedly connected to the fixing pipe 272. The fixing pipe 272 is also detachably connected to the second longitudinal frame 1192. With this configuration, by removing the second longitudinal frame 1192 from the fixing pipe 272 and removing the first longitudinal frame 1191 from the rear upright 1104, the rear frame 119 can be removed from the all-terrain vehicle 100, thereby converting the all-terrain vehicle 100 into a semi-enclosed model to meet usage requirements. At the same time, the fixing pipe 272 increases the contact area between the rear frame 113 and the second longitudinal frame 1192, thereby improving the connection stability between the second longitudinal frame 1192 and the rear frame 113.

[0045] Specifically, the cargo box 27 also includes a fastener 273 for mounting ropes. Both the fastener 273 and the fixing pipe 272 extend substantially along the length of the vehicle frame 11, and are fixedly connected. In some embodiments, the fastener 273 has several through holes 2731, facilitating the threading of ropes through it. Simultaneously, the ropes threaded through the fastener 273 can restrain the contents of the cargo box, preventing items from spilling out of the cargo box 27 during the operation of the all-terrain vehicle 100.

[0046] More specifically, the second longitudinal frame 1192 and the fixing member 273 are located on opposite sides of the fixing member 272, respectively. The mounting point of the second longitudinal frame 1192 and the fixing member 272 is located on the side of the fixing member 272 away from the second longitudinal frame 1192, and the fixing member 273 covers the mounting point of the second longitudinal frame 1192 and the fixing member 272. In some embodiments, the second longitudinal frame 1192 and the fixing member 272 are connected by installing screws in the mounting point. With the above arrangement, the fixing member 273 covers the screw, thereby hiding the screw and preventing accidental screw contact that could cause the tail frame 119 to fall off, thus improving the connection stability between the tail frame 119 and the fixing member 272; at the same time, it can prevent accidental screw contact that could cause screw deformation, thereby facilitating the removal or installation of the screw.

[0047] like Figure 6 and Figure 7 As shown, in one implementation, the canopy 242 includes a front canopy 2423 and a rear canopy 2424 located behind the front canopy 2423. The front canopy 2423 is mounted on the top bar structure 115, and the rear canopy 2424 is mounted on the rear frame 119. Specifically, the rear canopy 2424 has an installed state and a disassembled state. When the rear canopy 2424 is in the installed state, the rear frame 119 is connected to the rear pillar 104, and the rear canopy 2424 cooperates with the front canopy 2423 to seal the all-terrain vehicle 100, thereby improving the sealing performance of the canopy 242. When the rear canopy 2424 is in the disassembled state, the rear frame 119 is separated from the rear pillar 104. Through the above arrangement, the rear canopy 2424 can be installed and removed by removing and installing the rear frame 119, and the rear canopy 2424 can be installed and removed according to the usage requirements of the all-terrain vehicle 100, thereby improving the ease of installation and removal of the canopy 242. In some embodiments, the front roof 2423 and the roof bar structure 115 can be fixed by fasteners such as bolts, and the rear roof 2424 and the tail frame 119 can also be fixed by fasteners such as bolts.

[0048] It should be noted that the all-terrain vehicle 100 includes a first form with the cargo box 27 exposed and a second form with the cargo box 27 covered.

[0049] When the all-terrain vehicle 100 is in the first configuration, the rear frame 119 is separated from the cargo box 27 and the rear frame 119 is separated from the rear pillar 104. At this time, the rear roof 2424 is in a disassembled state, that is, the all-terrain vehicle 100 is a semi-enclosed model.

[0050] When the all-terrain vehicle 100 is in the second configuration, the rear frame 119 is connected to the cargo box 27 and the rear frame 119 is connected to the rear pillar 104. At this time, the rear roof 2424 is installed, meaning that the all-terrain vehicle 100 is a fully enclosed model.

[0051] As one implementation method, in order to meet the sealing requirements when the all-terrain vehicle 100 is a fully enclosed model, the vehicle body sealing structure 24 also includes a sealing element 246, and the front roof 2423 and the rear roof 2424 are sealed by the sealing element 246, thereby improving the sealing performance between the front roof 2423 and the rear roof 2424.

[0052] Specifically, to improve the waterproofness of the all-terrain vehicle 100, the rear end of the front roof 2423 is at least partially recessed to form a water channel 2423a. The water channel 2423a extends along the width direction of the frame 11 and is connected to the outside, thereby forming a drainage structure between the front roof 2423 and the rear roof 2424. This allows liquids such as water flowing between the front roof 2423 and the rear roof 2424 to flow out through the water channel 2423a to the outside, thereby improving the waterproof performance of the roof 242.

[0053] In this embodiment, the front end of the rear roof 2424 is at least partially located in front of the water channel 2423a and abuts against the front roof 2423, so that the rear roof 2424 and the front roof 2423 can cooperate with each other to form the roof 242 of the all-terrain vehicle 100.

[0054] More specifically, a first roof sealing surface 2423b is formed at the rear end of the front roof 2423. The first roof sealing surface 2423b is located behind the water guide groove 2423a. Along the height direction of the frame 11, the seal 246 is located between the first roof sealing surface 2423b and the lower surface of the rear roof 2424, thereby sealing the gap between the front roof 2423 and the rear roof 2424 and improving the sealing performance between the front roof 2423 and the rear roof 2424. The width of the first roof sealing surface 2423b is basically the same as the width of the front roof 2423 along the width direction of the frame 11, so that the seal 246 can basically completely seal the gap between the front roof 2423 and the rear roof 2424, preventing water and other liquids from flowing into the driver's compartment 20 from the gap between the front roof 2423 and the rear roof 2424.

[0055] As an optional implementation, a second roof sealing surface 2423c is formed at the rear end of the front roof 2423. The second roof sealing surface 2423c is located in front of the water guide groove 2423a. The portion of the rear roof 2424 located in front of the water guide groove 2423a is sealed to the second roof sealing surface 2423c by a seal 246. This seal 246 seals the gap between the front roof 2423 and the rear roof 2424, thereby improving the sealing performance between them. Specifically, along the width direction of the frame 11, the width of the second roof sealing surface 2423c is substantially the same as the width of the front roof 2423, allowing the seal 246 to essentially completely seal the gap between the front roof 2423 and the rear roof 2424, preventing water and other liquids from flowing into the driver's compartment 20 through this gap.

[0056] It should be noted that when the current roof 2423 simultaneously has a first roof sealing surface 2423b and a second roof sealing surface 2423c, two sealing elements 246 are provided. One sealing element 246 is used to seal the first roof sealing surface 2423b and the lower surface of the rear roof 2424, and the other sealing element 246 is used to seal the portion of the rear roof 2424 located in front of the water guide groove 2423a and the second roof sealing surface 2423c. It is understood that the front roof 2423 may also have one of the first roof sealing surface 2423b and the second roof sealing surface 2423c, in which case only one sealing element 246 is provided, and this application does not impose any restrictions.

[0057] It should be noted that when the current roof 2423 has both a first roof sealing surface 2423b and a second roof sealing surface 2423c, a triple seal can be formed between the front roof 2423 and the rear roof 2424, namely the seal between the first roof sealing surface 2423b and the rear roof 2424, the seal between the second roof sealing surface 2423c and the rear roof 2424, and the water guide groove 2423a, thereby improving the sealing effect of the all-terrain vehicle 100.

[0058] like Figures 8 to 10As shown, in one embodiment, the powertrain 15 includes an engine 151, an air filter 152, and a continuously variable transmission (CVT) 153. The CVT 153 is connected to the engine 151 and is used to change the transmission ratio between the engine 151 and the transmission mechanism 16. The air filter 152 is connected to the engine 151 and is used to filter the air supplied to the engine 151. An intake chamber 1123f is formed within the rear pillar 1104. The intake chamber 1123f communicates with the outside environment and is also connected to the air filter 152 and the CVT 153. Through this arrangement, outside air can enter the air filter 152 and the CVT 153 through the intake chamber 1123f, satisfying the intake requirements of the air filter 152 and the air-cooling requirements of the CVT 153. Furthermore, the air intake chamber 1123f is integrated into the rear pillar 1104, thus eliminating the need to install a separate air intake structure on the all-terrain vehicle 100, which helps to simplify the structure of the all-terrain vehicle 100 and improve the space utilization of the all-terrain vehicle 100.

[0059] Specifically, the rear pillar 1104 includes a first rear pillar 1104a and a second rear pillar 1104b distributed along the width direction of the frame 11. A first air intake chamber 1123g is formed in the first rear pillar 1104a, and a second air intake chamber 1123h is formed in the second rear pillar 1104b. The first air intake chamber 1123g is connected to the air filter 152, and the second air intake chamber 1123h is connected to the continuously variable transmission (CVT) 153. This arrangement allows the air filter 152 and the CVT 153 to intake air from both sides of the frame 11, thereby preventing the air volume on one side of the all-terrain vehicle 100 from being insufficient to meet the air intake requirements of the air filter 152 and the CVT 153, thus satisfying the air intake requirements of the air filter 152 and the CVT 153.

[0060] As an optional implementation, the first air intake chamber 1123g includes a first cavity 1123i and a second cavity 1123j, and the continuously variable transmission (CVT) mechanism 153 includes a first air intake port 1531b and a second air intake port 1531c. Specifically, the first air intake port 1531b is connected to the first cavity 1123i, allowing the CVT mechanism 153 to intake air from the first air intake chamber 1123g through the first air intake port 1531b. The second air intake port 1531c is connected to the second air intake chamber 1123h, allowing the CVT mechanism 153 to intake air from the first air intake chamber 1123g through the second air intake port 1531c. This configuration allows the CVT mechanism 153 to intake air from both sides of the frame 11, thereby further increasing the air intake volume of the CVT mechanism 153 to meet its air intake requirements.

[0061] More specifically, the second cavity 1123j is connected to the air filter 152. This arrangement allows the two cavities to respectively meet the air intake requirements of the continuously variable transmission (CVT) 153 and the air filter 152, thus eliminating the need for two separate cavities on the rear column 1104 for air intake of the CVT 153 and the air filter 152, and simplifying the structure of the rear column 1104. It should be noted that this application does not limit whether the first cavity 1123i and the second cavity 1123j are connected or separated.

[0062] It should be noted that when a first air intake chamber 1123g can meet the air intake requirements of the continuously variable transmission mechanism 153 and the air filter 152, there is no need to set a second air intake chamber 1123h in the second rear column 1104b, which helps to simplify the structure of the second rear column 1104b.

[0063] In one embodiment, the upper frame 110 further includes a central column 1103 connected to the upper frame body 1105, and the lower frame 11b further includes a central support column 11bb connected to the lower frame body 11bd. The central column 1103 is connected to the central support column 11bb. The central column 1103 is located between the front column 1102 and the rear column 1104, and the central support column 11bb is located between the front support column 11ba and the rear support column 11bc.

[0064] It should be noted that the all-terrain vehicle 100 also includes seat 19 (see reference). Figure 1 Seat 19 is supported by frame 11. The all-terrain vehicle 100 can be a double-cab or single-cab vehicle. When the all-terrain vehicle 100 is a double-cab vehicle, seat 19 includes a front seat 191 and a rear seat 192; when the all-terrain vehicle 100 is a single-cab vehicle, seat 19 only includes the front seat 191. Furthermore, compared to the double-cab vehicle, the single-cab vehicle's upper frame 110 does not include the center pillar 1103, and the lower frame 11b does not include the center support pillar 11bb; the remaining structures are the same. Moreover, this application uses a double-cab all-terrain vehicle 100 as an example for explanation.

[0065] In this embodiment, viewed from the length of the frame 11, the air filter 152 and the continuously variable transmission (CVT) 153 at least partially overlap. More specifically, the air filter 152 includes an air filter pipe 1521 communicating with the first air intake chamber 1123g, thereby allowing the air filter 152 to obtain air from the first air intake chamber 1123g through the air filter pipe 1521. The CVT 153 includes a first air intake pipe 1534 and a second air intake pipe 1535. The first air intake pipe 1534 communicates with the first air intake chamber 1123g, and the second air intake pipe 1535 communicates with the second air intake chamber 1123h, thereby allowing the CVT 153 to obtain air from both sides of the frame 11 in the width direction through the first air intake pipe 1534 and the second air intake pipe 1535 to meet the heat dissipation requirements of the CVT 153. With the arrangement of the first air intake chamber 1123g and the second air intake chamber 1123h, when viewed from the length direction of the frame 11, the air filter pipe 1521 and the first air intake pipe 1534 can at least partially overlap; when viewed from the width direction of the frame 11, the second air intake pipe 1535 and the first air intake pipe 1534 can at least partially overlap, and the second air intake pipe 1535 can also at least partially overlap with the air filter pipe 1521. Thus, the first air intake pipe 1534, the second air intake pipe 1535 and the air filter pipe 1521 can be arranged in a limited space, thereby improving the structural compactness of the air filter 152 and the continuously variable transmission mechanism 153, and improving the structural compactness of the all-terrain vehicle 100.

[0066] In this application, the all-terrain vehicle 100 includes a cargo box 27 located behind the rear pillar 1104. The lowest point of the air intake chamber 1123f is higher than the highest point of the cargo box 27, thereby making the air intake chamber 1123f located at a higher position on the all-terrain vehicle 100 to improve the wading performance of the all-terrain vehicle 100.

[0067] In one embodiment, the rear pillar 1104 includes a first sheet metal part 1123k and a second sheet metal part 1123m, which are fixedly connected to form an air intake cavity 1123f. In some embodiments, the first sheet metal part 1123k and the second sheet metal part 1123m are fixed by welding, thereby improving the connection stability of the first sheet metal part 1123k and the second sheet metal part 1123m. Furthermore, by welding at least a portion of the rear pillar 1104 with sheet metal parts, the processing difficulty of the rear pillar 1104 can be reduced, thereby improving the processing efficiency of the rear pillar 1104. In addition, the rear pillar 1104 formed by welding sheet metal parts can be processed into different shapes as needed, which is beneficial for forming the air intake cavity 1123f.

[0068] Specifically, a longitudinal plane 101 is defined that is perpendicular to the width direction of the frame 11 and passes through the center of the width of the frame 11. The second sheet metal part 1123m is closer to the longitudinal plane 101 than the first sheet metal part 1123k. This arrangement allows the second sheet metal part 1123m to be positioned closer to the driver's cab 20, while the first sheet metal part 1123k is positioned further away from the driver's cab 20.

[0069] More specifically, the first sheet metal part 1123k has an air intake opening 1123n that communicates with the outside, and the air intake chamber 1123f communicates with the outside through the air intake opening 1123n. This arrangement allows the air intake chamber 1123f to obtain outside air from outside the cockpit 20 through the air intake opening 1123n, so that the air intake chamber 1123f can obtain enough air to supply the air filter 152 and the continuously variable transmission 153.

[0070] More specifically, the body panel 12 includes an air intake grille 125, which covers the air intake opening 1123n and is fixedly connected to the first sheet metal part 1123k. This configuration allows the air intake grille 125 to shield and protect the air intake opening 1123n, thereby preventing debris from entering the air intake chamber 1123f. This improves the cleanliness of the air delivered from the air intake chamber 1123f to the air filter 152 and the continuously variable transmission (CVT) 153, thus extending the service life of the air filter 152 and the CVT 153.

[0071] As one implementation, the rear pillar 1104 also includes a waterproof structure 1123p, which prevents liquids such as water from entering the air intake chamber 1123f. Specifically, the waterproof structure 1123p is located inside the air intake chamber 1123f and is fixedly connected to the second sheet metal part 1123m. The waterproof structure 1123p divides the air intake chamber 1123f into a first chamber 1123i and a second chamber 1123j. The waterproof structure 1123p forms a drainage space 1123q that communicates with the outside. Along the length of the frame 11, the first chamber 1123i and the second chamber 1123j are distributed on both sides of the drainage space 1123q. With the above configuration, water and other liquids can be discharged from the intake chamber 1123f through the drainage space 1123q, so as to avoid water and other liquids affecting the normal operation of the air filter 152 and the continuously variable transmission mechanism 153, and to avoid water and other liquids causing damage to the air filter 152 and the continuously variable transmission mechanism 153, thereby improving the service life of the air filter 152 and the continuously variable transmission mechanism 153.

[0072] In this embodiment, the waterproof structure 1123p includes a first flange 1123r, which extends substantially along the first extending plane and defines a transverse plane 102 perpendicular to the length direction of the frame 11. The angle formed between the first extending plane and the transverse plane 102 faces the air intake opening 1123n, thereby blocking liquids such as water entering from the air intake opening 1123n. This prevents liquids such as water from entering the first cavity 1123i and the second cavity 1123j.

[0073] The first flange 1123r extends at least partially along the length of the frame 11 to form a mating portion 1123s. The mating portion 1123s is fixedly engaged with the first sheet metal part 1123k, thereby limiting the position of the waterproof structure 1123p, which facilitates the fixed connection between the waterproof structure 1123p and the second sheet metal part 1123m. Specifically, the mating portion 1123s also abuts against or connects with the air intake grille 125.

[0074] In this embodiment, the waterproof structure 1123p further includes a second flange 1123t, which extends substantially along the second extending plane and defines a reference plane 103 perpendicular to the height direction of the frame 11. The acute angle opening formed between the second extending plane and the reference plane 103 faces the drainage space 1123q. Specifically, multiple second flanges 1123t are provided. Along the length direction of the frame 11, multiple second flanges 1123t are located on both sides of the drainage space 1123q, and at least a portion of the second flanges 1123t are located between the drainage space 1123q and the first cavity 1123i, and at least a portion of the second flanges 1123t are located between the drainage space 1123q and the second cavity 1123j. This allows water and other liquids not blocked by the first flange 1123r to be blocked by the second flange 1123t and flow through the second flange 1123t to the drainage space 1123q, thereby discharging the water and other liquids to the outside. That is, the first flange 1123r and the second flange 1123t can achieve double waterproofing, thereby preventing water and other liquids from entering the air filter 152 and the continuously variable transmission mechanism 153.

[0075] It should be noted that after the gas enters the intake chamber 1123f through the intake opening 1123n, the gas needs to pass through the first flange 1123r and the second flange 1123t before it can flow to the air filter 152 and / or the continuously variable transmission mechanism 153, so that the first flange 1123r and the second flange 1123t can block the moisture in the gas.

[0076] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
